I have a siemens 200 amp main circuit breaker that bolts on. After the ice storm we had in nh a month ago, i can no longer turn the main breaker off on the panel. It moves but does not stay locked in the off position, it just returns to the open position when i let it go. Is there a quick fix or must it be replaced???

Fuses will blow if there is an overload. Breakers only trip if there is a short to ground. Since you replaced the fuse and it blew and tripped the breaker , I would check for a wire problem. Also check the elements that rodents haven't built nests ect...

it sounds to me like your hot tub has bugs take the control panel apart and clean the bugs out of it. if you have ants in the area they will get into the controls and cause it to trip out. i had similar problem with apump until i found the ants

realy only one major cause that I can think of short of the transformer intermitantly shorting out would be the Blower motor is causing your breaker to trip.....Have the motor checked out by doing an amp draw using an amp meter to determin starting amp and running amps....may be as simple as a start capacitor...Good luck.

With this cold weather, -- it is not likely tripping off because it is too hot!

Are you familiar with the history of this unit?-- Like has it tripped in the past during HOT weather? This might be a clue, that the circuit is really loaded close to its limit--

This leads to the next possibility: That the breaker is getting weak (They do after many hard starting loads! Now-- If you can get the system to start and run for just a few seconds-- can you put a Clamp around Amp meter on the wires?-- and read the full load current? How close is this to the rating of the circuit breaker? Is the breaker, and the wire size marginal?

Another thing to look for, is loose lug screws at the main fuses, and the Main contactors, and the motor leads--- for loose wires result in overheating, which raises the current, and leads to tripping, too.

How long ago was the condenser cleaned-- this leads to high amp draw too.

But the first thing would be to learn more about the age of the Main Breaker, and what the 'normal' run current is for that system.

You're unit is a 31/2 ton according to the numbers.Normally, breakers will only be in a half way posistion when tripped. Yes, under most conditions, the fuse will blow before the breaker trips. I have seen this many times, the breaker may be weak, burned, loose wires and so tighten wires, check the condition of the breaker.It sounds like the breaker even though it is 60 amps, is the problem and you should replace it with out hesitating. This will solve you're problem. When you pull the breaker out, look at the metal clips that snap in on the buss bar to see if they have been overheating.And the buss bar its self. You will know. I am sure this will take care of you're problem. Good Luck,Shastalaker7

No,you can not wire directly to a meter. All wiring must come through the circuit panel or sub panel.150 amps is sufficient to run what you describe. You may have a weak main breaker or loose wiring to these appliances. Place a amp meter on a incoming supply wire at the main, while you monitor amp draw have someone go around the house and turn on all these appliances. If it trips at less than 140 amps you have a bad main.I suspect you will find a bad neutral wire on one of these appliances.

I'm in a similar situation with a physical neccessity for a/c, year round, even though I live in temperate New Jersey. My husband is an A/C / Refrigeration tech & here's some things you can try to fix your Haier A/C.1.) Make sure you keep the area where the filter is clean, if you aren't using a filter, you are clogging the air flow much quicker, which can lead to freeze ups.2.) Due to how shoddy things are made now-a-days & with the storm coming through, you may have a conked out compressor or may have a small refrigeration leak, which can also cause freeze ups.3.) Make darned sure that the unit is level, if you find it is not, leave your unit off for at least 24 hours for the refrigeration gas & oil in the system to level off. Sadly, I do not know the model or type of Haier A/C you have & as I'd mentioned, things are no longer made to last like they once were & to get 3 years from a newer model is likely to be the best you can hope for. Haier is fairly decent with wanting to keep up customer morale & if it's a newer unit (younger than 18 months), they may help you to repair it for free or low cost. Good luck with that!
